The double-sided nature of the superfinishing lapping and honing process makes it possible to achieve parallel flatness on both sides of a part. Rather than lapping one side of the part, then flipping it over to lap the other side, both sides are worked simultaneously to create high parallelism.
In addition to our core capabilities we have recently added Flat & Cylindrical Lapping to our services in order to meet customer demands Items up to 6.00″ Dia. can be lapped obtaining tolerances of 1 Light Band Flatness with a surface finish of 1 Micro-inch CLA.
Polishing with a cloth or lapping plate requires the use of free abrasive, and is a very low damage process when performed properly. Plate material and cloth material are critical when polishing a particular sample as the properties of these substrates are important in the final polish quality of the specimen.
Double Side Grinding. Both sides of your part are simultaneously ground to precise dimensions for thickness, flatness, parallelism and microfinish. Thin parts are a natural application for double disc grinding. Melchiorre ELC 800. Twin wheel grinding, driven by 3 variable speed motors for maximum process control flexibility.
Lapping Machines – Polishing Machines – Grinding Machines View our wide selection of Lapping Machines. We offer refurbished machines from manufacturers like Lapmaster-Wolters, Speedfam, Engis Hyprez, PR Hoffman, Strasbaugh, Spitfire and many more.
SINGLE SIDE. Melchiorre single side machines have been designed to satisfy the customers'' requests for extremely precise and controlled lapping processes of flat surfaces. Depending on the slurry, it is possible to lap whatever material present in the industry, like cast .
For accurately grinding/polishing silicon wafers, optical glass, ceramics, quartz-crystal and other semiconductor materials. And also used for other hard and fragile flat materials. Main feature: 1.Equipped with high-powered transducer with the three-phase AC asynchronous motor, so realizing soft-start, soft-stop and so on.
Form grinding is a specialized type of cylindrical grinding where the grinding wheel has the exact shape of the final product. The grinding wheel does not traverse the workpiece. Internal grinding is used to grind the internal diameter of the workpiece. Tapered holes can be ground with the use of internal grinders that can swivel on the horizontal.
SGP utilizes both single and double sided grinding and polishing equipment to create the required precise surface quality, flatness, and parallelism required by our customers. Diameters of 0.005" and up to 18" are processed to optical quality achieving ¼ wave flatness in all types of materials.
In action, as the lapping wheel bore against the job, the grinding slide was reciprocated, rapidly, front to back; when one face had been lapped, by the right-hand turning disc, the motor was reversed and the other face finished by the other disk turning to the left - the makers claiming that this arrangement resulted in an improved parallelism of the two surfaces.
Feb 14, 2012· Since the only lapping compound we have sittin around is really coarse, i used Ajax, a brand of cleaner. Seems to be a mixture of something like diatomaceous earth, soap and sand. I mixed it with some kerosene, let the sand settle, poured it off, let the fines settle, poured it off, mix the fines with oil and go !

Dongguan gold to grind precision grinding machinery manufacturing co., LTD is affiliated enterprise toyama industrial group, mainly engaged in research and development, manufacturing, sales of high precision surface grinding machine, precision plane polishing machine, CNC equipment and consumable instead of related products.
Lapping. The abrasive embeds within the softer material, which holds it and permits it to score across and cut the harder material. Taken to a finer limit, this will produce a polished surface such as with a polishing cloth on an automobile, or a polishing cloth or polishing pitch upon glass or steel.
Currently, lapping and polishing with a loose abrasive have achieved high precision, but there are still problems with difficult-to-machine materials and the work environment. Noritake has developed a fixed diamond lapping wheel by new technology to improve them.

lapping, single side grinding (SSG), and SDSG. The lapping operation is illustrated in Fig. 2. A batch of wafers (for example, 20 wafers) is manually loaded into a lapping machine. The loaded wafers are then lapped by the abrasive slurry (typically a mixture of alumina and glycerine ) injected between two lapping plates rotating in opposite directions.

The two basic methods for gear grinding are form grinding (non-generating) and generation grinding. Form grinders use a disc wheel to grind both sides of the space between two gear teeth, and have an involute form dressed into the side of the wheel; a generating grinding wheel, on the other hand, is .
